Incremental impact test and simulation of prestressed concrete beam

摘要

This paper presents both experimental and analytical approaches on the dynamic behavior of a prestressed concrete (PC) beam under incremental impact loading. First, the weight-dropping test was performed in order to investigate the impact behavior of a PC beam under the condition that the weight is constant and the dropping-height increases. Second, the incremental impact analysis was developed in order to simulate the incremental impact test results by using an elastic-plastic dynamic analysis method based on a beam element model. Finally, the computational results are compared with the experimental ones.
